'y l' SPECIFICATION forming part of Letters Patent No. 530,526, dated December 11, 1894. Application filed April 18, 1892, Renewed May 5, 1894, SerialNo. 510,225# (No model.)

To all whom/it may concern: l Be it known that I, DANIELAL. HOLDEN, a

i citizen of the United States, residing in the city and State of New York, have invented an Improvement in Apparatus for Manufacturing Ice, of which the following is a speci- .ficatiorn The obje'ctvof the present invention is to consolidate chips of ice into blocks with rapidity so that such blocks of ice may be clear and free from bubbles of air.

In carrying'out my invention a vessel is employed containing water, and such vessel is exposed to a refrigeratin g action, so that ice is formed in layers upon layers of ice are scaled off progressively by the action of a cutter, and the ice chips or cuttings floating in the water are passed away over the edge of a pipeby which they are conveyed to a press, such press being prefer; ably in the form of a square tube or trunk containing a piston that acts upon the chips of ice in their moist condition to press them firmly together and the temperature is suchy that the ice rapidly solidies and the operations are continued progressively, the piston being drawn backiand a second cake consoli.- dated and the first one forced along in the trunk and delivered from the same in such a manner that it may be separated by sawing,

or otherwise, thus producing blocks of ice of uniform size and with great rapidity.

In the drawings Figure 1 is a vertical s ection illustrating the improved apparatus, and Fig. 2 is a cross section of the solidifying trunk. Y

The vessel A is of any suitable size orshape, preferably cylindrical and it is adapted to the` freezing Operation; for which purpose pipes B containing ammonia or similarfrigerific material are employed by which the vessel A is reduced to the proper temperature. When the vessel A is made in the form represented it is advantageous to surround the same with a non-conducting jacket C, and within the lvessel A is a stand pipe D open at Ithe top end, and' water is admitted into the `vesselA and around the stand pipe D by any suitable supply pipe, preferably the pipe E at the bot-- tom of the vessel with a regulating cock thereon, so that the water may dow in progressively the vessel, and the 'sides of the cake of ice,

and float .the ice and such ice passes over the top of the stand pipeD and falls down through the same. v v

It 'is to be understood that the vessel A is preferably of sheet metal and there are within the'same the revolving scraper-s or cutters F' of any suitable character. I have represented the same as upon a 'fork supported by the shaft G which is rotated by competent power, and the scrapers or as' the water freezes upon the of the vessel A. y

The solidifying truuk H is preferably horizontal and rectangular and it contains the piston I, and there is upon perK n to which the ice crystals or chips can be admitted from the stand pipe D-by a' slide valve L or any other suitable device, .or if desired the crystals or chips of'ice can fall directly from the stand pipe D into thehopper K.

I prefer-to make the piston I hollow andto perforate the operative end ofthe same and to cover the end of the piston with suitable woven material such as bagging,` as repre'- sented at 3, and the piston I receives motion from a crank and connecting rod or by a screw or any other suitable power, so that the piston rod' gives motion tothe piston I and carries the ice crystals or chips along within the solidifying trunk Il and applies the necessary pressure to cause the particles of ice to adhere together in the presence of moisture'aud freeze into a solid block, and I remarkthat a jacket maybe provided at Naround the solidifying trunk H tofrigeriic material may be admitted to reduce the temperature of the solidifying trunk and permit the solid freezing ofthe ice. During the Operation'of pressing the block of ice, the surplus water will run through the perforated piston and out at the open end of the solidifying trunk and the same may be caught in any suitable vessel and returned to the vessel A in its cold conditionso as easily to be reduced to the temperature necessary for forming ice.

It is advantageous to employ friction clamps O set up by suitable springs P- at two or more as itis proj ectedfrom the end of the solidifying trunk H, in order interior su rface the trunk Hi a hopwhich ammonia or other that the ice may be detained lwhile the'necessary pressure is exerted upon the same byl the piston, and as the-blocklof ice issues from Y the solidifying trunk its movement may be arrested by a stop R, and I prefer to employ a circular saw S hung in the 'frame T and rapidly rotated by suitable power, so that by moving the frame T the saw may be brought across the block of `ice to saw olf a section thereof, which block will slip down betweenv the saw and the stop and can be received upon any suitable trough or conveyer. Y In this manner 'blocks of uniform size are rapidly frozen and delivered from the machine; and the refrigerating actionis very direct upon the ice, so that when itis scaled oi the temperature thereof is suicientlylow tocause the consolidation within the trunk H under the pressure of the piston I. It will be apparent thatin the present improvements I overcome a great diiiiculty that has heretofore existed in ice making machin,- ery, because the ice is a comparatively poor conductor and the thicker the layer of ice the moreintense must be the cold to continue "the freezing operation. i

In the present improvements a compara# tively thin layer of intensely cold ice is produced and the same is immediately scaled oi and another layer is frozen, so that a greater quantity of ice is producedin the same time by the frigeric action. I am aware that elorts have been made to obtain ice by freezing the 'same upon a mov.- ing surface and scaling the ice ol and subjecting the same to pressure. y In my improvement the ice as it is scaled off the congealing surface is allowed to float and the water at the top becomes the coldest and the ice floats o ver the edge of the stand pipe, and the water that accompanies the same lessens the'quantity of air present with the ice. Hence when the ice is pressed and nsolidated it is clear and free from air bubes. I claim as my invention- 1. The combination in an ice making apparatus of a water holding vessel, means for reducing the temperature and forming ice on caused to accumulate and overflow with only the adhering water, substantially as set forth. 3. The combination with the refrigerating device of a water holding vessel, on the sur: face of which ice is formed, agradual water supply to said vessel, and means for cutting or scalin'g oi the ice progressively so that it floats and is dis`charged by the accumulation, substantially as specified. 4. The combination with the refrigeratjng device of a water holding vessel, on the surthat it floats, a surface therefrigerating 'vessel, whereby the ice chipser scales are face of which ice is formed, a gradual water y supply to said vessel, or scaling oi the ice floats and isdischarged by the accumulation. a trunk into which the ice scales are received in their moist condition and a piston and means for moving the same to consolidate the and means for cutting icel substantially as specified.

5. The combination device of a water holding vessel, on the. surface of which ice isformed, a 'gradual water supply to said vessel, and means for cutting or scaling oi the ice progressively so that it oats andis discharged by the accumulation, a'trunk'into which the ice scales are received in their moist condition and a piston and means for moving the same to consolidate the ice, and a saw for sawing ol the ice into blocks as projected from the trunk substantially as specified.
